FIELD AND BACKGROUND OF THE INVENTION

The present invention relates to shoe insert pads and, in particular, itconcerns a breathable ventilated shoe pad.

In order to maintain the cleanness of the interior of a shoe and providebetter comfort, the interior of the shoes often requires the use of shoepad. At the moment, the majority of the shoe pads seen on the marketonly possess one feature, cushioned padding. The shoe pads of the priorart do not effectively ventilate or breath. There are some shoe padsthat perform a certain level of ventilation. However, these shoe padspossess some structural complications, high manufacturing cost and areeasy to break.

There is therefore a need for a breathable ventilated shoe pad.

SUMMARY OF THE INVENTION

The present invention is a breathable ventilated shoe pad.

According to the teachings of the present invention there is provided, abreathable, ventilated one-piece shoe pad comprising: a) a shoe pad bodyhaving multiple ventilation holes; and b) an air bag attached to thebottom surface of the shoe pad body, the air bag having correspondingventilation holes aligned with the multiple ventilation holes of theshoe pad body.

According to a further teaching of the present invention, the shoe padbody includes a compartment that contains the airbag.

According to a further teaching of the present invention, there is alsoprovided foam padding deployed inside of the air bag.

According to a further teaching of the present invention, the air bagextends from a heel portion of the shoe pad body for a distance of halfthe length of the shoe pad body.

According to a further teaching of the present invention, a heelthickness of the air bag is thicker than the rest of other parts.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention is a breathable ventilated shoe pad.

The principles and operation of a breathable ventilated shoe padaccording to the present invention may be better understood withreference to the drawings and the accompanying description.

By way of introduction, the practical new design of the presentinvention provides a type of breathable, ventilated one-piece shoe padhaving a main body that includes many ventilation openings. On thebottom surface of the main body an air bag is attached. The surface ofthe interface at which the air bag attaches to the main body inconfigured with many ventilation openings that correspond to theopenings at the main body. The structure of this practical new design isvery simple, it is cost-efficient in manufacturing and the productitself is durable. When utilized inside the shoe, the air bag creates anair convection flow and exhausts the foul stale air out of the shoeduring each step of the user. This helps to keep the foot dry.

The purpose of the present invention is to aim at the deficiency of thecurrent technique and thereby provide some kind of simple structured andeasy to use ventilating shoe pad.

In order to fulfill the above-described purpose, the present inventionprovides a shoe pad body the top of which includes multiple ventilationholes. The bottom of the shoe pad body attaches to the top surface of anair bag. There are multiple corresponding openings in between the shoepad body and the top surface of the air bag where the air bag contactsthe shoe pad body. When the shoe pad body and the air bag are beingattached, the corresponding ventilation holes are aligned so as toprovide airflow to and from the air bag through the ventilation holes.

The described shoe pad body is configured with a compartment in thebottom surface. The air bag is attached to the pad body inside thecompartment.

The described air bag may be filled with substantially any sponge orother soft cushion material Preferably, the described air bag extendsfrom the heel of the shoe pad body for a distance of about half thelength of the shoe pad body. It will be understood that an embodiment inwhich the air bag extends further and even up to the full length of theshoe pad is within the scope of the present invention. Further, the airbag may be configured so as to be thicker at the heel end than the restof length of the air bag.

Some of the effective benefits of the present invention are that theoutstanding simple structure of the ventilated shoe pad of the presentinvention lowers the manufacturing cost and ventilated shoe pad of thepresent invention is not as easily damaged as those of the prior art.

When it is inserted into the shoe, the presence of the air bag duringwalking causes the internal air to ventilate. Therefore, it generates aconvection effect (air flow) upon each step a user makes. In doing so,it exhausts the filthy or stale air out of the shoe and keeps the footdry.

Referring now to the drawings, FIGS. 1-6 relate to a preferredembodiment of a breathable ventilating shoe pad of the present inventionthat includes a shoe pad body 10 and an air bag 20. Due to theperspiration of the foot that forms near the middle area of the sole ofthe foot, the shoe pad body 10 includes multiple ventilating holes 101on the middle area of the length of the pad body 10. There is acompartment 11 configured in the bottom surface of the shoe pad body 10and an air bag 20 attaches inside of the compartment 11 with glue (orsubstantially any other suitable attachment arrangement) to securelyconnect the air bag 20 to the shoe pad body 10.

Preferably, a sponge 21, which is soft and stores more air, is deployedinside the air bag 20 so as to substantially fill it. It should be notedthat the air bag may be filled with substantially any suitable materialthat provides the required cushioning and air exhausting features neededfor the proper functioning of the breathable ventilating shoe pad of thepresent invention. Further, the material inside the air bag may bedeployed by substantially any method such as, but not limited to beinginjected into the air bag.

The portion of air bag 20 that is the contacting interface surfacebetween the air bag 20 and shoe pad body 10 includes multipleventilating holes 201 corresponding to, and aligned with, theventilation holes 101 on the shoe pad body 10. During process ofwalking, with each step the user's foot presses against the air bag 20such that the air inside of the air bag 20 interacts with the airentering the shoe.

Due to the pressure concentrated on the heel part of the shoe pad duringthe process of taking a step, the length of the air bag 20 could bedesigned to extend from the shoe pad body 10 to the middle part of theshoe pad body 10. Further, the thickness of the air bag 20 at the heel22 portion is greater than the rest of length of the air bag 20. Itprovides the shoe pad with better anti-shock effects and higher volumeof airflow.

Once the breathable, ventilating shoe pad of the present invention isplaced inside of a shoe, air is forced from the air bag 20 during theprocess of walking by the user's foot pressing against shoe pad. Whenthe user lifts his/her foot up, the air bag 20 changes to a negativepressure condition. The air outside of shoe pad is drawn into the airbag 20. Accordingly, substantially every full step a user makes willgenerate airflow out of and into the air bag, and therefore the shoe, sothat the foot can be maintained in a dry and comfortable condition.

Additionally, it should be noted that in order to ensure that air fromoutside of the shoe interacts and flows with the air from the inside ofthe air bag 20, some exhaust pipes or passages (not shown), may beinstalled at an appropriate area of the shoe. Further, to avoid there-entry of stale air that is being exhausted from inside the, theexhaust pipes may be configured with a one-way valve (not shown).

It will be appreciated that the above descriptions are intended only toserve as examples and that many other embodiments are possible withinthe spirit and the scope of the present invention.
